-	bool "Watchdog Timer Support"
-	---help---
-	  If you say Y here (and to one of the following options) and create a
-	  character special file /dev/watchdog with major number 10 and minor
-	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
-	  subsequently opening the file and then failing to write to it for
-	  longer than 1 minute will result in rebooting the machine. This
-	  could be useful for a networked machine that needs to come back
-	  on-line as fast as possible after a lock-up. There's both a watchdog
-	  implementation entirely in software (which can sometimes fail to
-	  reboot the machine) and a driver for hardware watchdog boards, which
-	  are more robust and can also keep track of the temperature inside
-	  your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
-	  in the kernel source.
-
-	  The watchdog is usually used together with the watchdog daemon
-	  which is available from
-	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
-	  also monitor NFS connections and can reboot the machine when the process
-	  table is full.
-
-	  If unsure, say N.
-
-if WATCHDOG
-
-config WATCHDOG_NOWAYOUT
-	bool "Disable watchdog shutdown on close"
-	help
-	  The default watchdog behaviour (which you get if you say N here) is
-	  to stop the timer if the process managing it closes the file
-	  /dev/watchdog. It's always remotely possible that this process might
-	  get killed. If you say Y here, the watchdog cannot be stopped once
-	  it has been started.

- *	Theory of Operation:
- *		The Watch-Dog Timer is provided to ensure that standalone
- *		Systems can always recover from catastrophic conditions that
- *		caused the CPU to crash. This condition may have occured by
- *		external EMI or a software bug. When the CPU stops working
- *		correctly, hardware on the board will either perform a hardware
- *		reset (cold boot) or a non-maskable interrupt (NMI) to bring the
- *		system back to a known state.
- *
- *		The Watch-Dog Timer is controlled by two I/O Ports.
- *		  443 hex	- Read	- Enable or refresh the Watch-Dog Timer
- *		  043 hex	- Read	- Disable the Watch-Dog Timer
- *
- *		To enable the Watch-Dog Timer, a read from I/O port 443h must
- *		be performed. This will enable and activate the countdown timer
- *		which will eventually time out and either reset the CPU or cause
- *		an NMI depending on the setting of a jumper. To ensure that this
- *		reset condition does not occur, the Watch-Dog Timer must be
- *		periodically refreshed by reading the same I/O port 443h.
- *		The Watch-Dog Timer is disabled by reading I/O port 043h.
- *
- *		The Watch-Dog Timer Time-Out Period is set via jumpers.
- *		It can be 1, 2, 10, 20, 110 or 220 seconds.

- *	ALi M7101 PMU Computer Watchdog Timer driver
- *
- *	Based on w83877f_wdt.c by Scott Jennings <linuxdrivers@oro.net>
- *	and the Cobalt kernel WDT timer driver by Tim Hockin
- *	                                      <thockin@cobaltnet.com>
- *
- *	(c)2002 Steve Hill <steve@navaho.co.uk>
- *
- *  This WDT driver is different from most other Linux WDT
- *  drivers in that the driver will ping the watchdog by itself,
- *  because this particular WDT has a very short timeout (1.6
- *  seconds) and it would be insane to count on any userspace
- *  daemon always getting scheduled within that time frame.
- *
- *  Additions:
- *   Aug 23, 2004 - Added use_gpio module parameter for use on revision a1d PMUs
- *                  found on very old cobalt hardware.
- *                  -- Mike Waychison <michael.waychison@sun.com>

- *
- *	Code contributed by: R. Seretny <lkpatches@paypc.com>
- *	Documentation obtained by R. Seretny from SuperMicro Technical Support
- *
- *	To enable Watchdog function:
- *	 1. BIOS
- *	  For P4SBx:
- *	  BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
- *	  For P4DPx:
- *	  BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
- *	 This setting enables or disables Watchdog function. When enabled, the
- *	 default watchdog timer is set to be 5 minutes (about 4’35�). It is
- *	 enough to load and run the OS. The application (service or driver) has
- *	 to take over the control once OS is running up and before watchdog
- *	 expires.
- *
- *	 2. JUMPER
- *	  For P4SBx: JP39
- *	  For P4DPx: JP37
- *	  This jumper is used for safety.  Closed is enabled. This jumper
- *	  prevents user enables watchdog in BIOS by accident.
- *
- *	 To enable Watch Dog function, both BIOS and JUMPER must be enabled.
- *
- *	The documentation lists motherboards P4SBx and P4DPx series as of
- *	20-March-2002. However, this code works flawlessly with much newer
- *	motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
- *
- *	The original iTCO driver as written does not actually reset the
- *	watchdog timer on these machines, as a result they reboot after five
- *	minutes.
- *
- *	NOTE: You may leave the Watchdog function disabled in the SuperMicro
- *	BIOS to avoid a "boot-race"... This driver will enable watchdog
- *	functionality even if it's disabled in the BIOS once the /dev/watchdog
- *	file is opened.

- * Watchdog Timer Configuration
- *
- * The function of the watchdog timer is to reset the system
- * automatically and is defined at I/O port 0443H.  To enable the
- * watchdog timer and allow the system to reset, write I/O port 0443H.
- * To disable the timer, write I/O port 0441H for the system to stop the
- * watchdog function.  The timer has a tolerance of 20% for its
- * intervals.
- *
- * The following describes how the timer should be programmed.
- *
- * Enabling Watchdog:
- * MOV AX,000FH (Choose the values from 0 to F)
- * MOV DX,0443H
- * OUT DX,AX
- *
- * Disabling Watchdog:
- * MOV AX,000FH (Any value is fine.)
- * MOV DX,0441H
- * OUT DX,AX
- *
- * Watchdog timer control table:
- * Level   Value  Time/sec | Level Value Time/sec
- *   1       F       0     |   9     7      16
- *   2       E       2     |   10    6      18
- *   3       D       4     |   11    5      20
- *   4       C       6     |   12    4      22
- *   5       B       8     |   13    3      24

- *      wd#2 - 7.2 ms;

- *
- * Version 0.1 (99/04/15):
- *		- first version
- *
- * Version 0.2 (99/06/16):
- *		- added kernel timer watchdog ping after close
- *		  since the hardware does not support watchdog shutdown
- *
- * Version 0.3 (99/06/21):
- *		- added WDIOC_GETSTATUS and WDIOC_GETSUPPORT ioctl calls
- *
- * Version 0.3.1 (99/06/22):
- *		- allow module removal while internal timer is active,
- *		  print warning about probable reset
- *
- * Version 0.4 (99/11/15):
- *		- support for one more type board
- *
- * Version 0.5 (2001/12/14) Matt Domsch <Matt_Domsch@dell.com>
- *		- added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT
- *
- * Version 0.6 (2002/04/12): Rob Radez <rob@osinvestor.com>
- *		- make mixcomwd_opened unsigned,
- *		  removed lock_kernel/unlock_kernel from mixcomwd_release,
- *		  modified ioctl a bit to conform to API

- * PC Watchdog Driver
- * by Ken Hollis (khollis@bitgate.com)
- *
- * Permission granted from Simon Machell (smachell@berkprod.com)
- * Written for the Linux Kernel, and GPLed by Ken Hollis
- *
- * 960107	Added request_region routines, modulized the whole thing.
- * 960108	Fixed end-of-file pointer (Thanks to Dan Hollis), added
- *		WD_TIMEOUT define.
- * 960216	Added eof marker on the file, and changed verbose messages.
- * 960716	Made functional and cosmetic changes to the source for
- *		inclusion in Linux 2.0.x kernels, thanks to Alan Cox.
- * 960717	Removed read/seek routines, replaced with ioctl.  Also, added
- *		check_region command due to Alan's suggestion.
- * 960821	Made changes to compile in newer 2.0.x kernels.  Added
- *		"cold reboot sense" entry.
- * 960825	Made a few changes to code, deleted some defines and made
- *		typedefs to replace them.  Made heartbeat reset only available
- *		via ioctl, and removed the write routine.
- * 960828	Added new items for PC Watchdog Rev.C card.
- * 960829	Changed around all of the IOCTLs, added new features,
- *		added watchdog disable/re-enable routines.  Added firmware
- *		version reporting.  Added read routine for temperature.
- *		Removed some extra defines, added an autodetect Revision
- *		routine.
- * 961006       Revised some documentation, fixed some cosmetic bugs.  Made
- *              drivers to panic the system if it's overheating at bootup.
- * 961118	Changed some verbiage on some of the output, tidied up
- *		code bits, and added compatibility to 2.1.x.
- * 970912       Enabled board on open and disable on close.
- * 971107	Took account of recent VFS changes (broke read).
- * 971210       Disable board on initialisation in case board already ticking.
- * 971222       Changed open/close for temperature handling
- *              Michael Meskes <meskes@debian.org>.
- * 980112       Used minor numbers from include/linux/miscdevice.h
- * 990403       Clear reset status after reading control status register in
- *              pcwd_showprevstate(). [Marc Boucher <marc@mbsi.ca>]
- * 990605	Made changes to code to support Firmware 1.22a, added
- *		fairly useless proc entry.
- * 990610	removed said useless proc code for the merge <alan>
- * 000403	Removed last traces of proc code. <davej>
- * 011214	Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT <Matt_Domsch@dell.com>
- *              Added timeout module option to override default

- *           12/4 - 2000      [Initial revision]
- *           25/4 - 2000      Added /dev/watchdog support
- *           09/5 - 2001      [smj@oro.net] fixed fop_write to "return 1" on success
- *           12/4 - 2002      [rob@osinvestor.com] eliminate fop_read
- *                            fix possible wdt_is_open race
- *                            add CONFIG_WATCHDOG_NOWAYOUT support
- *                            remove lock_kernel/unlock_kernel pairs
- *                            added KERN_* to printk's
- *                            got rid of extraneous comments
- *                            changed watchdog_info to correctly reflect what the driver offers
- *                            added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
- *                            WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
- *           09/8 - 2003      [wim@iguana.be] cleanup of trailing spaces
- *                            use module_param
- *                            made timeout (the emulated heartbeat) a module_param
- *                            made the keepalive ping an internal subroutine
- *                            made wdt_stop and wdt_start module params
- *                            added extra printk's for startup problems
- *                            added MODULE_AUTHOR and MODULE_DESCRIPTION info
- *
- *
- *  This WDT driver is different from the other Linux WDT
- *  drivers in the following ways:
- *  *)  The driver will ping the watchdog by itself, because this
- *      particular WDT has a very short timeout (one second) and it
- *      would be insane to count on any userspace daemon always
- *      getting scheduled within that time frame.

- *
- * Watchdog Timer Configuration
- *
- * The function of the watchdog timer is to reset the system automatically
- * and is defined at I/O port 0120H and 0121H.  To enable the watchdog timer
- * and allow the system to reset, write appropriate values from the table
- * below to I/O port 0120H and 0121H.  To disable the timer, write a zero
- * value to I/O port 0121H for the system to stop the watchdog function.
- *
- * The following describes how the timer should be programmed (according to
- * the vendor documentation)
- *
- * Enabling Watchdog:
- * MOV AX,000AH (enable, phase I)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000BH (enable, phase II)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000nH (set multiplier n, from 1-4)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000mH (set base timer m, from 0-F)
- * MOV DX,0121H
- * OUT DX,AX
- *
- * Reset timer:
- * MOV AX,000mH (same as set base timer, above)
- * MOV DX,0121H
- * OUT DX,AX
- *
- * Disabling Watchdog:
- * MOV AX,0000H (a zero value)
- * MOV DX,0120H
- * OUT DX,AX
- *
- * Watchdog timeout configuration values:
- *		N
- *	M |	1	2	3	4
- *	--|----------------------------------
- *	0 |	0.5s	5s	50s	100s
- *	1 |	1s	10s	100s	200s
- *	2 |	1.5s	15s	150s	300s
- *	3 |	2s	20s	200s	400s
- *	4 |	2.5s	25s	250s	500s
- *	5 |	3s	30s	300s	600s
- *	6 |	3.5s	35s	350s	700s
- *	7 |	4s	40s	400s	800s
- *	8 |	4.5s	45s	450s	900s
- *	9 |	5s	50s	500s	1000s
- *	A |	5.5s	55s	550s	1100s
- *	B |	6s	60s	600s	1200s

- *	E |	7.5s	75s	750s	1500s
- *	F |	8s	80s 	800s 	1600s
- *
- * Another way to say the same things is:
- *  For N=1, Timeout = (M+1) * 0.5s
- *  For N=2, Timeout = (M+1) * 5s
- *  For N=3, Timeout = (M+1) * 50s
- *  For N=4, Timeout = (M+1) * 100s

- *           9/27 - 2001      [Initial release]
- *
- *	Additional fixes Alan Cox
- *	-	Fixed formatting
- *	-	Removed debug printks
- *	-	Fixed SMP built kernel deadlock
- *	-	Switched to private locks not lock_kernel
- *	-	Used ioremap/writew/readw
- *	-	Added NOWAYOUT support
- *	4/12 - 2002 Changes by Rob Radez <rob@osinvestor.com>
- *	-	Change comments
- *	-	Eliminate fop_llseek
- *	-	Change CONFIG_WATCHDOG_NOWAYOUT semantics
- *	-	Add KERN_* tags to printks
- *	-	fix possible wdt_is_open race
- *	-	Report proper capabilities in watchdog_info
- *	-	Add WDIOC_{GETSTATUS, GETBOOTSTATUS, SETTIMEOUT,
- *		GETTIMEOUT, SETOPTIONS} ioctls
- *	09/8 - 2003 Changes by Wim Van Sebroeck <wim@iguana.be>
- *	-	cleanup of trailing spaces
- *	-	added extra printk's for startup problems
- *	-	use module_param
- *	-	made timeout (the emulated heartbeat) a module_param
- *	-	made the keepalive ping an internal subroutine
- *	3/27 - 2004 Changes by Sean Young <sean@mess.org>
- *	-	set MMCR_BASE to 0xfffef000
- *	-	CBAR does not need to be read
- *	-	removed debugging printks
- *
- *  This WDT driver is different from most other Linux WDT
- *  drivers in that the driver will ping the watchdog by itself,
- *  because this particular WDT has a very short timeout (1.6
- *  seconds) and it would be insane to count on any userspace
- *  daemon always getting scheduled within that time frame.
- *
- *  This driver uses memory mapped IO, and spinlock.

- * Default clock division ratio is 5.25 msecs. For an additional table of

- * time.
- *
- * In order for this to work reliably we need to have HZ set to 1000 or
- * something quite higher than 100 (or we need a proper high-res timer
- * implementation that will deal with this properly), otherwise the 10ms
- * resolution of a jiffy is enough to trigger the overflow. For things like
- * the SH-4 and SH-5, this isn't necessarily that big of a problem, though
- * for the SH-2 and SH-3, this isn't recommended unless the WDT is absolutely
- * necssary.
- *
- * As a result of this timing problem, the only modes that are particularly
- * feasible are the 4096 and the 2048 divisors, which yeild 5.25 and 2.62ms
- * overflow periods respectively.
- *
- * Also, since we can't really expect userspace to be responsive enough
- * before the overflow happens, we maintain two seperate timers .. One in
- * the kernel for clearing out WOVF every 2ms or so (again, this depends on
- * HZ == 1000), and another for monitoring userspace writes to the WDT device.
- *
- * As such, we currently use a configurable heartbeat interval which defaults
- * to 30s. In this case, the userspace daemon is only responsible for periodic
- * writes to the device before the next heartbeat is scheduled. If the daemon
- * misses its deadline, the kernel timer will allow the WDT to overflow.

- *	SMsC 37B787 Watchdog Timer driver for Linux 2.6.x.x
- *
- *      Based on acquirewdt.c by Alan Cox <alan@redhat.com>
- *       and some other existing drivers
- *
- *	This program is free software; you can redistribute it and/or

- *	2 of the License, or (at your option) any later version.

- *
- *	(C) Copyright 2003-2006  Sven Anders <anders@anduras.de>
- *
- *  History:
- *	2003 - Created version 1.0 for Linux 2.4.x.
- *	2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
- *             features. Released version 1.1
- *
- *  Theory of operation:
- *
- *      A Watchdog Timer (WDT) is a hardware circuit that can
- *      reset the computer system in case of a software fault.
- *      You probably knew that already.
- *
- *      Usually a userspace daemon will notify the kernel WDT driver
- *      via the /dev/watchdog special device file that userspace is
- *      still alive, at regular intervals.  When such a notification
- *      occurs, the driver will usually tell the hardware watchdog
- *      that everything is in order, and that the watchdog should wait
- *      for yet another little while to reset the system.
- *      If userspace fails (RAM error, kernel bug, whatever), the
- *      notifications cease to occur, and the hardware watchdog will
- *      reset the system (causing a reboot) after the timeout occurs.
- *
- * Create device with:
- *  mknod /dev/watchdog c 10 130
- *
- * For an example userspace keep-alive daemon, see:
- *   Documentation/watchdog/watchdog.txt

- *
- *  03/96: Angelo Haritsis <ah@doc.ic.ac.uk> :
- *	Modularised.
- *	Added soft_margin; use upon insmod to change the timer delay.
- *	NB: uses same minor as wdt (WATCHDOG_MINOR); we could use separate
- *	    minors.
- *
- *  19980911 Alan Cox
- *	Made SMP safe for 2.3.x
- *
- *  20011127 Joel Becker (jlbec@evilplan.org>
- *	Added soft_noboot; Allows testing the softdog trigger without
- *	requiring a recompile.
- *	Added WDIOC_GETTIMEOUT and WDIOC_SETTIMOUT.
- *
- *  20020530 Joel Becker <joel.becker@oracle.com>
- *  	Added Matt Domsch's nowayout module option.

- *           4/19 - 2001      [Initial revision]
- *           9/27 - 2001      Added spinlocking
- *           4/12 - 2002      [rob@osinvestor.com] Eliminate extra comments
- *                            Eliminate fop_read
- *                            Eliminate extra spin_unlock
- *                            Added KERN_* tags to printks
- *                            add CONFIG_WATCHDOG_NOWAYOUT support
- *                            fix possible wdt_is_open race
- *                            changed watchdog_info to correctly reflect what the driver offers
- *                            added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
- *                            WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
- *           09/8 - 2003      [wim@iguana.be] cleanup of trailing spaces
- *                            added extra printk's for startup problems
- *                            use module_param
- *                            made timeout (the emulated heartbeat) a module_param
- *                            made the keepalive ping an internal subroutine
- *
- *  This WDT driver is different from most other Linux WDT
- *  drivers in that the driver will ping the watchdog by itself,
- *  because this particular WDT has a very short timeout (1.6
- *  seconds) and it would be insane to count on any userspace
- *  daemon always getting scheduled within that time frame.
